memblock tests: fix compilation errors

Do 'make -C tools/testing/memblock', get the following errors:

memblock.o: In function `memblock_find_in_range.constprop.9':
memblock.c:(.text+0x4651): undefined reference to `pr_warn_ratelimited'
memblock.o: In function `memblock_mark_mirror':
memblock.c:(.text+0x7171): undefined reference to `mirrored_kernelcore'

Fixes: 902c2d91582c ("memblock: Disable mirror feature if kernelcore is not specified")
Fixes: 14d9a675fd0d ("mm: Ratelimited mirrored memory related warning messages")
